Abstract (en)
[origin: US6479138B1] A film includes a core layer including a linear random alpha-olefin/vinyl aromatic copolymer; and first and second outer layers including an olefinic polymer; the film having Young's modulus between 50,000 and 200,000 psi, free shrink between 40 and 80% at 240° F., and shrink tension of between 50 and 400 psi, or a shrink force of between 20 and 180 grams, at 240° F. First and second intermediate layers including an ethylene copolymer having a melt index less than 2.0 can be optionally included. Alternatively, a film includes a core layer including an ethylene copolymer having melt index less than 2.0; first and second intermediate layers including a linear random alpha-olefin/vinyl aromatic copolymer; and first and second outer layers including an olefinic polymer; the film having properties as disclosed above.
